[AAAI 2026 Oral] PosterVerse: A Full-Workflow Framework for Commercial-Grade Poster Generation with HTML-Based Scalable Typography

</div>

🌟 Highlights

• PosterVerse

• PosterDNA

• We propose PosterVerse, a full-workflow method that integrates blueprint creation, graphical background generation, and unified layout-text rendering, enabling the creation of posters with aesthetically sophisticated layouts and text-dense designs for commercial-grade use.

• We propose PosterDNA, the first commercial-grade and text-dense poster generation dataset with fine-grained HTML-based specifications, designed to support modular training and validation with high-quality samples.

• PosterVerse allows users to generate commercial-grade posters solely from textual prompts.

• Extensive experiments demonstrate that PosterVerse can generate visually appealing posters with aesthetic designs, precise text, and well-crafted layouts, meeting the standards of commercial-grade posters.

📺 Inference

Step 0: Download all model files from the Model Zoo

Step 1: Download the Flux.1 dev model

Step 2: Using PosterVerse to generate posters:

CUDA_VISIBLE_DEVICES=<gpu_id> python pipe_infer.py \
--stage1_model_path /path/to/Blueprint Creation/model \
--stage3_model_path /path/to/Unified Layout-Text Rendering/model \
--lora_local_path lora_model \
--request_prompt '能不能给我来一张以绿色为主色调、画布大小1080×1920的立春节气海报？风格清新唯美，画面要有树叶、樱花、古风人物等元素。主标题"立春"，配上古诗文案，营造春意盎然的感觉，体现出节气特点，展示春天的美好。'
